I agree with all the troubles, but I found that my disposable contacts (single use) work better under lights. They are monocular... distance only, whereas my regular contacts each have a different perscription (one for closer distance, one for further) which many people have. Not having to compensate for the different focal points might be one less thing for the brain to have to deal with along with the improper or dim lighting.

I wear Acuvue Oasis contacts which are just like the ones you describe and while they are infinitely better than glasses at night for me they still don't help much on the worst lit courts I've had to play on. I'm spoiled in that the lights on our home courts are pretty good and that there are only two rows of lights on them to deal with.
